To allfzruhom'z't 'may concern:4 v 4 Be it known that I, JOHAN FERDINMID J ULIUs .'CLnrmNT'soN, a. citizen of Sweden, and a resident of Malm, Sweden, have 1nvented a new and useful Improvement in Reversing-Gear for Propelle1-Shafts, of which the following is aspecification. t

This invention relates to a novel improvement in reversing gear for propeller shafts foroutboard motors. y

The object of the invention is to provide 'a simple and reliable construction of reversing gear for said purpose by using only one shaft and avoiding separate couplings between the toothed wheels.

vThe invention is illustrated in the accom-` panying drawing z--Figure 1 is a vertical, sectional view of the whole arrangement: Fig.d2 is a side view of -a part ofthe 'steering and reversingv lever mechanism. Fig. 3 is a horizontal, `sectional view, taken' through the motorshaft and its sleeve at lever." Fig. 4 is a horizontal, sectional ,key 5 on the prolongation 4 is fitted. The

view,- taken through @the motor shaft and its sleeve farther down.

The motor 1 is `rov'ided with a vertical, hollow'crank vsha 2, in which the upper end of a' prolongation'4 of saidshaft is vertically slidable.

vertical oove 3 is provided, in which a sleeve 8 surrounding the shaftl carries .a

bracket in which' the horizontal 'pivot pin 9 fora steering and reversing lever 6 is' mounted said lever having 'a forked part embracing the bracket and the sleeve 8.

The lever 6 movable vertically i-n ai` knewn -vwaynafter looseninglthe catch 7 and `it is pivotally connected with vtwo arms 10 (Figs. 2 and 3) which at their lowerends are connected rwith al ring 12 or the like y which is prevented from sliding vertically by means of a sleeve for the like 11. When'- the lever 6 is moved vertically around the pivot pin 9, that is perpendicular to the shaft 4 this latter will `be lifted 0r lowered.'Y

The sleeve 8 isconnected with the casing 113 by means of a pipe 23 surrounding the shaft 4. The casing .113 carries the rudder- 28- and bearings for the propeller-shaft 16. Two`bevel gear wheels-14, 15 'are mounted o n the shaft 4 and' xed thereto axially and radially.l One of these wheels is placed oneach side -of another bevel'gear wheel 17.

In the crankshaft a fastened to the-propeller shaft 16. When 'either in such a way that both wheels 14,.

l5 are brought out of engagement with the wheel 17 or so that the wheel 15 is lengaged with. the same instead of the wheel 14, as shown inthe drawing. The motor is in a known way suspended over the stern ofthe boat by means `of a stirru 1Q and a clamping screw 20. The boat is'steered by mea-ns of the lever 6 by' moving the same horizontally, and the sleeve 8` is at the upper end. provided with a'liange 21 that is made to turn in a groove formed between a ring 22v or the like and a recess in the motor casing.

By the construction described loose gear wheelsare done away with and all the advantages mentioned above are gained.

lHaving thus described the invention, I claim l y -1. Reversing gear for propeller shafts in i, ,connection with outboard'` motors Acomprising a prolongation of the crank shaft of the' motor, said prolongation being made to slide axially and provided with two bevel gear wheels |fixed Aon the sameaxially and radially, one on each side of a bevel gearA wheel fastened on the propeller shaft, a steering lever connected with the prolongationv by means of arms in such a way that one or the other of thevxed gear wheels on-said prolongation will be .brought into or out of engagement. with the wheel 011 the propeller'shaft. .v

42. :In apparatus of the character described, a substantially vertical -power substantially `a rightV angle to the' driveshaft, a bevel gear carried bythe propeller shaft, a vertically movable. drive shaft hav-I `ing 4a slidable keyed engagement with the power shaft, a propeller shaft arranged at v '3. In apparatus of the character described, a suitably supported substantially verticalbearing, apowershaft journaled in the bearing, a: vertically movable drive shaft having a slidable keyed engagement with the power shaft, a horizontally turning sleeve pivoted upon the bearing, a vertical swinging lever pivotally connected With the sleeve to, turn it and connect it with the drive shaft to raise and lower it, a gear casing carried by the sleeve, a pro peller shaft carried by the gear casing, a

vbevel gear secured to the propeller shaft, l0 and upper and lower bevel gears carried by the drive shaft and arranged upon opposite sides of the 'rst named bevelA gear.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
